The commands have the following bit format: 0000 0000 000T 000R
• T 1 = Trigger hold measurement
• R 1 = Reset min and max values
The Command will be acknowledged by the response message on Modbus and by a short message.
• Show sensor

Start / stop command is in the following bit format position: 000S 0000 0CCC CCCC
• C Sensor ID
• S
• 1 = Starts fast LED blinking
• 0 = Stops fast LED blinking
Data written has to specify a known sensor ID.
Example: 0x1017 means “Start fast LED blinking of sensor with ID 23”
When sensor is addressed correctly, common response will follow
When the sensor ID is not used in the system, and exception response with Modbus exception code 03h
“Illegal data value” will follow. (If fast LED blinking was already active, it will be stopped)
Return to normal display content is possible by sending the stop command.
